Oracle Linux 3 / 4 / 5 : fetchmail (ELSA-2007-0385)

An updated fetchmail package that fixes a security bug is now
available for Red Hat Enterprise Linux 2.1, 3, 4 and 5.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

Fetchmail is a remote mail retrieval and forwarding utility intended
for use over on-demand TCP/IP links, like SLIP or PPP connections.

A flaw was found in the way fetchmail processed certain APOP
authentication requests. By sending certain responses when fetchmail
attempted to authenticate against an APOP server, a remote attacker
could potentially acquire certain portions of a user's authentication
credentials. (CVE-2007-1558)

All users of fetchmail should upgrade to this updated package, which
contains a backported patch to correct this issue.
